Use the routine to set the CIMPLICITY user
and corresponding password (if there is
one) for the project from which resources are about to be
requested,

Do this before you request any CIMPLICITY
resources.

When the application requests a
CIMPLICITY resource requiring a login, these set parameters will be
used to provide the login action with data.

These parameters remain set until
cleared by an application.

Therefore, if the system timeouts
should cause a logout, a subsequent request would again reference
this data for login.

A logout can happen after all requests for
resources have been removed.

Note: If the provided data is not valid, no
attempt is made to obtain the login information via GUI or
otherwise, and no error is given. These routines can be called
multiple times to change the data that should be referenced on
future login attempts without having to clear any data already
set.
